Seminar Details
This paper describes the technical benefits of building an integrated marine navigation or positioning system around a highly accurate inertial reference sensor. An accurate and stable positioning system requires three key components: heading, motion, and position. An integrated system allows for improved results because most of the timing errors can be removed. Using accurate gyros and accelerometers at the center of the system can provide extended dead reckoning time with predictable accuracies. The INS at the center of this type of system can be added with different positioning sensors such as GNSS, acoustics, or relative position sensors. This paper will discuss the benefits of integrating INS with different positioning sensors and the performance enhancements that can be expected.
